Okay, so I FINALLY got the Becker iPod cable adaptor for Becker stereo systems.
(Just under $140 US shipped from Europe).



It does NOT function with the Crossfire OEM Becker stereo with NAV.

The Becker 2660, 6 Disc, CD-Changer DOES function with the Crossfire OEM Becker Stereo with NAV.
(Changer is a reconditioned unit out of a Porsche, so I got it for under $300).

So, I had a cable that didn't work and a changer that did... what to do... what to do...

Well, I decided I wanted my iPod input more than the CD-Changer, so...

1. I separated the green and blue plugs from both the iPod Remote Kit cable and the CD-Changer cable. I kept the blue plug from the iPod Remote Kit and the green cable from the CD-Changer. I then assembled these two plugs as they just clip together.

2. I tapped the +12VDC power from the green CD-Changer cable jack into the iPod Remote Kit cable green jack to power the iPod Remote Kit cable. This allows the iPod to charge properly. I used a meter to verify polarity even though the CD-Changer cable was color coded properly (red for positive [+] and black for negative/ground [-]).

3. After hooking this combo cable into the OEM Stereo head unit, the CD-Changer came to life as always, except it had no audio.

4. I plugged in my iPod and the audio was piped in with the changer selected on the head unit.

Pros & Cons

Pros -

1. I have my iPod audio.

Cons -

1. I have no CD-Changer use other than a dummy box to trick the head unit into using it's only AUX input (CD-Changer in).

2. I must control my iPod from the iPod itself. Not a huge downer as the remote kit allows enough cable to position the iPod on the center console at my fingertips.

Things to resolve...

No CD-Changer audio... at one time I had seen a small auxiliary input box that allowed two inputs. One primary and one secondary. As long as the secondary was active, the primary was cut off. When the secondary was turned off or had no signal the primary was put back on. I have yet to locate this box again... but my search continues. EDIT! I found it here! ... and it's only $30... whoo-hoo! (I'll probably have to cut off the RCA heads and hard wire it into the two cables as a single harness).

Overall, this was cheaper than a new NAV head unit install with iPod control.

Things to note: If you do this yourself make sure you have ALL DAY to do it. You WILL have to remove lots of panels to get the CD-Changer cable to the back of the vehicle as I did. (I installed the CD-Changer in the 'first aid kit' recess under the cargo cover in the hatch area. In order to run this cable to the front, you have to remove the lower right side soft panel, right kick panel, right door sill plate, right side seat and then pull up the carpet enough to run your wire along the factory wiring path which runs down the center of the right floor pan area.) I was VERY impressed with the design/engineering and craftsmanship put into this vehicle.

I will be posting pictures and specific pins in a few days... I'm still recovering from the install.
